Zimecterin is the brand of the compound containing both Ivermectin and praziquantel.
Dosage is the issue with a compound you may get too much or not enough of either medication when using it. Best to stay with one or the other alone unless your body weight matches the % ratio of the two different meds in the compound .
To play it safer use one or the other but not the compound. Make sure you know how the math works ML to mg and by body weight. If not find a knowable person who does. Be sure you don't have any other underlining conditions or other Meds that will interact badly.
That's all I will say ….
